ImDrawFlags_AAEnds and ImDrawFlags_StrokeLegacy ok. (the most important ones).
ImDrawFlags_UseTexForRoundCorners ok.
ImDrawFlags_AAFill, ImDrawFlags_AAStrokes: for primitives: only for selected ones taking flags params. Haven't added the flag to all functions because it feels like a fringe use case.
ImDrawFlags_TextNoPixelSnap supported in RenderText(), per-prim (9417)
- test overestimate before testing more expensive details when testing if stroked ngon is actualy filled
- Note: not a common function, but the test harness is using this to draw a triangle, which makes it show up in profiling
- revert texture selection to use just (inlined) round()
- the values were tuned to hide texture selection pops on small thickness
- since we're using super sampling for the problematic range, the tweaks are not necessayr anymore
- the ImDrawListFlags_AntiAliasedFill and ImDrawListFlags_AntiAliasedLines flags work again
- added non-AA rendering for polyline and convex poly filled
- do not use corner textures when AA is not used
- Add missing no-AA for single line case
- added CalcArcStepAndCount() to calculate the step size consistently
- _AddRectTinyRounding: fixed stem placement with thin lines (clamping was needed for an older version of the function)
- _AddRectTinyRounding: fixed texture coordinates (uses if inner/outer were reversed)
- use polygon instead of circle when calculating baked corner rounds (the circle was more accurate but looked different size comparet to polyline)
- use macro to test if rounding value is worthy
- changed threshold to be a bit smaller (for smoother handling of small radius), and relative to fringe
- Use inline array + AddPolyline/AddConvexPolyFilled for triangle and quad
- do less computation for detecting small shape rendering
- add IM_UNLIKELY for very unlikely branches
- changed truncated tests to use macro, and inline the computation in debug builds (~15% was spent on calling the functions)
- inlined the common rectangle cases in AddRect() for debug build speed up
- fixed how super sampled line textures are generated (and documented wrong assumption)
- switched to more samples and smaller thickness range
- tweaked super sampled texture selection to hide the texture changed better
- added animated thickness to demo to make it easier to evaluate thickness visual progression
- added super sampled textures in thickness range [1..3] to avoid visual pop
- fixed bug where fringe size was not properly applied in _AddRectTinyRounding
- optimized _AddRectTinyRounding to use less vertices
- changed _AddRectTinyRounding to use similar texturing logic as lines
- remove unused fractional line width texture
